SFEGIFIGATION forming part of Letters Patent No. 758,296, dated April 26, 1904..

Application'filed May 23, 1902. Serial No. 108,716. (No model.) I

To all whom, it may concern:

Be it'known that LWILLIAM P.BIl.ET'I", a citizen of the United States, residing at Decatur, in the county of Macon and State'of Illinois, have invented a new and useful Windmill, of which the following is a specification.

My invention relates to that class known as the "upright or vertical wheel windmill; and the obgects of my improvement are, first, to provide means for the automatic lubrication of all of the bearingsof the power-transmitting mechanism of the windmill-head; second, to provide means for protecting the bearings and the oil-reservoirs fromwhich they are lubricated from snow, rain, and dust, and,

third, to provide means by which the surplus oil that drips from the bearings'is returned to the reservoirs for repeated use. I attain theseob ects by the mechanism illustrated in the accompanying drawings, in which.-

.Figure 1 is a top view of the windmill-head with the top section A of the incasement re-- moved; Fig. 2, a vertical section'of the Windmill-head on the line a b, Fig. .1; Fig. 3, a vertical section on lines d, Fig, 2; Fig. 4, aiview f of the pitman as seenwhen looking-in the direction indicated by the arrow in Fig. 2 and as the upper part of it appears in Figs. '11 and 13; Fig. 5, a top 'view of the reciprocating wrist-pin and parts made integral with it as a means for its anchorage in the cross-head oilreceptacle; Fig. 6', a top view of= a modified form of cross-head in which. the wrist-pin is 1 made integral therewith; Fig. 7 a side view of the cross-head shown in Fig; 6; Fig.8, a vertical section through Figs. 6 and 7 on the line f g and through ,the lower part of a modified form of an incasement adapted to this form of cross-head; Fig.9, a top View of an oil-elevating device as seen'when looked at from above when it" is on top of the crankdisk; Fig. 10, a sideview of Fig. 9; Fig. 11, a vertical section through a modified form of incasement on a line corresponding to linecd in Fig. 2; Fig. 12, avertical section through the upper part-of the incasementon line efd of .Fig. 2, and Fig. 13 is a vertical section through another modified formof anincasement on the same line that Fig. 11 is shown. Similar letters and figures refer to sim lar parts throughout the several news.

First referring to Figs. 1, 2, and 3, the main frame of the windmill-head is seen'to comprise an incasement made in two sections, of which A is the main or body part and A the cover portion of the incasement. The main part A comprises at its upper portion the lateral extensionor shaft-carrying bracket B and at its lower extremity the vertically-apertured anchorage portion D, upon the inside of the incasement below the bracket B the oil-reservoir (J, and also within and extending from the bottom upward the cross-head guides 1 and 1'. The wheel-shaft 15 and the crankshaft 12 have their bearings 16, 16", and 12' anchored mainly in the reservoir B of the bracket'B, and the crank-disk 12" is secured to the inner end of the shaft 12, so as to'overhang th'ereservoir C and contact with the lubricant contained therein, and on the wheelshaft 15 is mounted the pinion 14:", so as to -mesh with the internal gear 1 1', which is preferably an integral. part of the crank-disk 12". The collar 21 on shaft l2 in connection with the crank-disk retain this'shaft in axial position,- and collars 21' on shaft 15 serve the double purpose of lubricating the bearings adjacent thereto and of maintaining the axial position of the wheel-shaft. The bearings 12,16',and 16" are preferably made integral with the cross-connecting bars 17 and 17 and the longitudinal bars 18 and '18 and are removably anchored on'the bridges 19 and 19' in the reservoir B.

The pitman 1 is pivoted at its upper end -on the wrist-pin 1 1 of the. crank-disk 12", and at its lower end onthe wrist-pin 1 in the crosshead reservoir E, immediately below the upper pitman-bearing, and preferably made integral.therewith, is the concave oil-deflecting --'shelf 31, sloping so as'to drain toward the crank-disk, and is provided. with the downwardly-projecting 'lip 30, which stands close to the crank-disk and causes all oil flowing from thedeflector31' to fall into the reservoir C, the inner wall 13 of which if projected upward would strike the shelf 31' close to the body part of the pitman, with the lip 30 pro- 'jecting into the reservoir C'with a considerable space between it and the wall 13, so that 'no oilwill fall outside thereof when the pitman is at the upper portion of its stroke. The

V cross-head oil-reservoir E is provided with the I do overflow duct 8 above the level of the pitmancross-head is continuously lubricated from the reservoirs D and E. By the use of the short hinged parts or chains (shown at 23 and 24 in Fig. 3) it is readily seenthat oil from the extreme bottom portion of the reservoir 0 may a. be taken up and distributed to all of the bearings adjacent to the crank disk and that it is not necessary for the reservoir to be so closely located as .tocause the disk to contact with the oil therein when these auxiliary oil-elevating parts are used.-

In operation the reservoirs B, C, D, and E are filled with oil, and as the crank revolves "in contact with the oil in the reservoir C a liberal quantity of oil will fiow from the slowlymoving disk to all parts connected therewith.

.The oil flowing onto the end of the bearing 12 will be mainly conducted by the incline 16 into the groove 15" on the top thereof, from which a portion of it will go to the interior of. the bearing through suitable ducts and the surplus will overflow into the reservoir B below, from which this surplusis conducted back to the reservoir'Cby overflowing the wall 35. Thus a constant level of oil is maintained'in reservoir B, in contact with which the collars 21 will rotate and elevate a portion thereof and cause it to flow onto the ends of the bearings adjacent thereto and through suitable ducts to the interior of the bearings. The oil that flows from the crank onto the upper end of the pitrnan and wrist-pin 14: will as it drips or flows therefrom be-defleeted by the shelf 31', so as to also drain back into the reservoir (3. Thus itis seen that during the operation of the windmill there is a continuous and liberal circulation of oil from the reservoir below the crank-disk up and through all of the bearings and frictional parts of the windmill-headrthereabove and a return of the oil to the reservoir for repeated or continuous use, while the lower end oi the pitman and cross-head are continuously lubricated from reservoirs l) and E withou waste of oil, as described above.

1i amore liberal flow of oil is desired than will result from the use of the short flexible parts 22 24, (shown. in Fig. 3,) the device shown in Figs. 9 and 10, which is provided with the bucketQS or acontinuous chain or link belt, may be substituted therefor, as

shown in Fig. 12, in which26 represents an idler near the bottom. within. the reservoir for retaining the chain in position. With the con sented as being elevated from the reservoir in the bottom part of the incasement to the crankdisk, from which it is distributed to all of the bearings, as above described When the reservoir C is dispensed with and the endless chain 27 used to elevate the oil, the bottom portion of the incasement is modified, as shown in Figs. 8 and 11, so that there is room for the idler 27 between the anchorage portion of the incasement and the outer wall of the reservoir below the crank-disk. In connection with the forms shown in Figs. 8, 11, and 13 the pitman and cross-head are-modified to conform to the requirements of these changed conditions, the cross-head requiring no oil-reservoir in connection therewith to lubricate the wrist-pin; but instead thereof the oil-duct 32 is made through the deflector 31', which leads into the channel 34, which is adapted to conduct the surplus oil that flows from the upper pitman bearing to the cross-head wrist-pin below, and immediately below this wrist-pin is the oildeilector 9', which in connection with, the cross-head prevents the oil from drippinginto the vertical aperture of the pivot portion 1) and conducts it into the reservoir adjacent thereto for continuous use.

In connection with the modified form of incasement, pitman, and cross-head (shown in Fig. 11) it may be desirable in some special cases to use a pump instead of the endlesschain to elevate the oil, which can be done as sl1own in Fig. 13, in which 28 is a pump-cylinder, 28 apump-plunger carried by the crosshead 2", which is adapted to raise clear of the cylinder on the upstroke and to enter it on the downstroke, forcing the oil that enters at the top from the, reservoir D" out through 1 the pipe 29, so as to discharge from the nozzle 29 onto the crank-disk, from which it is'dis- 'tributed to the frictional parts of the windmill-head, as above described.

To make the incasement air-tight, so as to protect the reservoirs and working parts of the-head from rain, snow, and dust during storms, a gasket, as 37., is placed between the sections of the incasernent.
